Question

From the following data find the mean,median and mode.The weight s of nine nursery class children are given. 30 kg,24 kg,26 kg,25 lg,27 kg25 kg,28 kg​

Answer 1

Answer:

mean = 26.43 (approx)

median = 26

mode = 25

Step-by-step explanation:

Mean = ( sum of values ) / ( number of values )

         = ( 30 + 24 + 26 + 25 + 27  +25 + 28 ) / 7

         = 185 / 7

         ≈ 26.43  (approx)

Median

Sorted values are:  24, 25, 25, 26, 27, 28, 30

There are 7 values so the middle value is the (7+1)/2 = 4th value.

The median is that middle value, so median = 26.

Mode

25 occurs twice, while all other values occur only once.

That is, 25 is the most frequent value.

So mode = 25.
